Only a suggestion if it appeals to everyone. My brother/sister and I use to, (and every now & then still do) play a game we simply call "Person." One person has someone in mind and the others ask yes or no questions until someone guesses. You can ask anything that can be answered yes or no. I'm thinking for space purposes (if it matters) maybe we can allow one person to post up to three questions in the same post (or not? I don't know, Maybe with so many playing it'll go quickly).
It could go on because there are so many fields of celebrity to cover BUT then again, there would be more than two/three people playing and it could go fast, so don't know if maybe an initial hint might be necessary.

Anyway, just an idea. I'm open to whatever everyone wants.
